If Brazil can produce ethanol from sugar cane, then why not Cuba, or Mexico, or Venzuela or <insert your tropical country of choice>?. Venezuela doing ethanol would be a bit like Iran going nuclear! Come to think of it, the Middle East could be reforested with sugar cane (for ethanol) and Jatropha (for biodiesel)...
The federal government from Brazil is transfering the sugarcane ethanol thecnology to Cuba. I suppose that Cuba can be a ethanol producer and start to export ethanol. But USA will not buy it while Fidel is alive...

Some countries as Germany and Japan show interest at buy Brazil's ethanol. The problem is that Brazil can produce maybe enough ethanol only for Brazil's consumption. So, not enough ethanol to export. And when the sugar's price goes up the ethanol productions goes down...

I think that the sugarcane's ethanol EROEI is positive. The problem with the USA's ethanol program is that is based at corn and the EROEI appear be negative.

Sorry the bad english, my native language is portuguese.

And if Brazil, one of the world's great agricultural powerhouses can't produce any for export, even with an automobile ownership ratio far short of North America or Europe, how is the rest of the world suppossed to grow enough?

(Oh, your English is fine, communicated what you wanted, and is far better than my second language ability)
